I’ve done the TCL (1st stage) with Glenmore Lodge, also in Aviemore and can thoroughly recommend them too, especially since food and accomodation is included, along with trails ‘on campus’~ the course itself is good fun and certainly gets you thinking… it’s one thing to be able to ride for yourself, but thinking how to educate and motivate others is a stimulating challenge.
For the TCL, I wouldn’t worry too much about steezy skills… its pretty basic, though the MBL brings in a fair few more elements, but its still fairly fundamental to a keen rider.
Depending where you are based, you may be able to get partial or full funding… I left it too late to get re-imbursed for the training course, but got 50% back for the first aid and assessment.
Have fun!!
